Fixing a Slipstream Annoyance
This may not be an issue for other riders with smaller hands. But the head of the hex screw on the Slipstream's brake levers rubs against the bottom of my hand. After, years of riding a Vanguard, my riding position has gotten pretty relaxed and my hands seem to naturally slip to the bottom of the grips where the bolt head will rub the palm.
The fix is simple just remove the bolts with a hex driver and screw them back in from the inside of the brake lever instead of the outside where they were installed. The picture shows the bolt in its new position where it can't rub your hand.
